David Cameron is getting this so wrong because he and his ministers are completely out of touch. His Government is preparing to give 13,000 millionaires a tax cut worth an average £100,000, while more than half a million households that are home to a disabled person will lose £700.

And he doesn’t understand the real impact this policy will have on families. In Hull, where I launched the campaign last week, 4700 people will be affected by the Bedroom Tax – and there are just 73 properties available for them to move into.
